sion installed in automobiles, to change the; speed of the machine and toreverse the mo` tion as well. f

y The objects of our invention are; to provide a gear transmission operated by a lever in such manner that all shifting canv be` made with one hand by moving saidlever, to provide shaft brackets which can be inf` stalledrin the gear housing to carry the counter shaft and the reverse shaft;to pro-- vide a lock in the gear shifting arms, such that only one of the shifting `arms can be operated at the same time; to installa socket in the housing of the gears to carry `the actuating ball of the operationlever; to

provide a friction to prevent the gear shifting arms and lingersv from moving under the vibration of the Vmachine;to install a drive shaft'carrying a movable gear lwhich will engage with the drive shaft of the en-` gine and deliver the motion'thereof :direct to the wheels; to install an oiler within the gear'housing which will collect the oilwhen the apparatus is in motion and conduct the y l y i which is free to rotate about the `shaft 8 same to the bearings. l

We attain these obj ects by the mechanism illustrated in the accompanying drawings, in which: f

Figure 2 is an elevational 'view of the gears'withoutthe gear housing, .taken along the line 9A .in Figure 1, ylooking tothe front.

` plates, the upper which is held in theiywheel `and the lowerbeing mounted lin the drive shaft at the center.

Similar numerals referto similar parts throughout the severalviews.

`.The f1y-wheel 1 is directly connected to the crank-shaft ofthe engine, but is installed within the gear housing 2. Theplate 3 is setin the fly-wheel in the ymanner shown `in'Figu're 1,' and the sections 4 are provided in thecircumference of the plate to-fit' about the pins 5 set in the fly-wheel, in order that the plate may move with*` the rotation'of the wheel. f

The shaft 8 carrying the flywheel, eX- tends through. the 4shaft 7 and enters a bearing provided in the end of `the shaft 16. All parts except rthe flywheel are free torotate on the shaft 8 as said shaft forms abearing only. This will be seen by the inner dotted line in Figure l'of the drawings. The shaft` 7 rotates about the shaft 8, being constructed as a sleeve, and' having the pinion 9 fastened thereto.` The clutch ring 12`is keyed b-ut movable along the sleeve 7 caused by the action of the lever 13 and the spring 11. When the clutch is jin operation, the vspring y11 n forces the clutch members' together. In this. case the flywheel forms one member of the clutch and delivers the motion to the sleeve 7. f

The clutch 6 is mounted on the shaft 7 inserted within. The pinion!) is pressed and `keyed on the shaft 7 andthe shoulder 10 is provided as a' rest forthe clutch spring 11 which is coiled.- about thefshaft y7. The clutch ring 12 is built-on the movablememberof. the clutch and the .fingers of the clutch operating` arm 13y areassembled in the groove provided in the ring. `lith 'the `clutch arm mounted on the shaft 14 which extends throughthe housing'and connected to the foot pedal,vit will be understood `how theemovable member of the clutch can 4beoperated against the y clutchk spring. l

Roller bearings 15 are mounted on the end ofthe shaft 8 rwhich is inserted in the shaft 16 in the manner shown in Figurel 3,

l which forms a bearing for both shafts. The

.berof the clutch 1-9 isprovided andy aligned.

to engage with the female memberQG which is built in the gear 18 as showniin Figure 3 Vof the drawings.

The shifting fingers 21 are assembled in the i par-ts forming the i clutchf at ithat point can be madel to operate? WiththeI clutch" engaged, the shafts 7- an'd'16 rotate the ysame and thiscreates the-highgearfof thema-' chine.

A second gear 22 ismountedon the shaft, l 16, subject to rotate therewithandlm'ovable longitudinally in the same manner-- as the gear "18 The shifting fingers'f23f'are as# sembled in the lgroove 24, Vand'govern-'the sliding' 'motien of the 4gear along ,the-l shaftlf Two brackets 25 `and26 are installed inthe gear housing andheld'l-'iirplace by boltsf'inf a sentedy throughv the housing at the proper points. v Thebrachetsareprovided to carryV` the counter shaft27 andthe revers'efsh'aft l28.`

Gears 29,30` and l'fare mounted ioni-the, counter shaft and keyed to rotate-With the same. These gears are of different sizes, as Will-be seen byf Figurel of the drawings, the arrangement beiiigl to provide for the different speeds', of the machine. Tivo gears 82'and'33 arefmounted'andileyed to the re?,-

The gear 29 is in meshwiththe pinion y9, through `which the motion-is-deliveredto the counter shaft and -all `gears -mounted thereon.

VVhenthe gear 18 is moved to mesh With the gear 30 onA the counter'shaft; intermediate speed isdelivered to `Lthe` Wheelsof the machine, it being understood that clutch member in the'gear 18'vvillmove vizvith the gear and avvayfrom the malemember With which it is marde toengage. When the-gear 22 is moved to mesh with thepge'arV 31.5011 the counter f shaft, l'ovv" speed is delivered tothe Wheels of the machine, land`u'fhen saidigear 22 ,ismoved to mesh 'Withthe gearl 33y on thefV balland* socket joi-ntforms-the actuating.

Neitherof the shifting arms can be moved Whilethe lever 34 is` engaged with both `in thfmanner shown in Figure 5. In such case the ball 36 Would lock both arms from movingvthebracket 37. This is provided so that only one gear can be shifted at a time. TheA bra'clzety is built onto counter shaft bracket 26, extending vclear from all gears as shown in Figure 2'ofthe drawings. The balls 38 are compressed againstthe-shifting rod or arms, by thefspring`=39 c acting 1onr the plateLO, inthe manner shown in'Figure 4l When it is desired-'to shiftk the' gears; the lever is moved'to the si'de of` the proper shift'- ing arm, andthus is disengaged-froml the re-f m'aini'ng arm-as Will be seenfby Figure-( When the leveris in this position, thear-m With-vvhich it is engaged, fcan bemoved longitudinally inthe 'bracket "3T, lthefballk lockl being 'moved tothe circular-portion? of the arm Which is stationary` duringtheop!V eration.v .Fromfthe lastdesc'riptiom it'Will bey seen how only one shifting lever canbe moved atA the same time.v It Will also be -seen` that all" gears inp mesh \vvill have tol be' moved to neutr'ah before the leverba'n engage'` in the same.

`All `the gears runin oil), the housing being so provided as vto holdoil for lthef mecha'- nism-to operatein." A 'catch-pan et1'isin4` stalled in; the housingvvith anynumber of conductors 42j leading the oil td thevarions bearings about the gears andshafts. The oilis kcollected inthe pan or collectorfwhen the gears andfl'yevvheel are inv motion, as the motion of the parts' Within the housing cause the oil to spatter about and fpart there! of Will fall-in the pan' and/return to the'bearings through the conductors.
